Referrer warning pop-ups

It would be great if we could have warnings pop up on the referrer card file when they are selected as a referrer on a patient's file. We keep tabs on how they want reports sent and any treatment preferences e.g. thumb
in/out for splints etc - if this could pop up when we go to write a new letter or when they are added as the referrer it would serve as a reminder to our therapists.
